CLOSURE Filed Dec. 14, 1929 77 I INVENTOR M'Mda/ i3. rid/"fa PatentedFeb. 7, 1933 MICHAEL B. ANDRIE, OF GRAND RAPIDS, MICHIGAN,,ASSIGNOR TOi3. J'Anvrs coM- PANY, F GRAND RAPIDS, MICHIGAN, A CORPORATION OFMICHIGAN cLoscnn Application filed December 14, 1929. Serial No.413,996.

The main objects of this invention are to provide a closure for radiatornecks, oil tanks and the like which may be quickly applied or removed,is effective in sealing the opening and is very compact.

A further object is to provide a closure having these advantages whichis simple and economical in its parts and at the same tlme strong anddurable.

Objects relating to details and economies of my invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary vertical section through a radiator closureembodying my invention.

Fig. 2 is an inverted view of the cap re- 'moved from the radiator neck.

Fig. 3 is a plan view of the radiator neck.

Fig. 4 is a bottom view of the latch memher.

In the embodiment illustrated, 1 represents a motor vehicle radiator and2 its shell. The filler neck 3 is provided with an inturned flange 4: atits upper end conformed to provide a seat for the gasket 5. On the inneredge of the flange 4 I form opposed segmental cammed keepers 6 havingdepending stops 7 at corresponding ends thereof.

The cap 8 is provided with an annular rib or bead-like gasket seat 9opposed to the gasket seat of the neck and adapted to engage the gasketwhen the cap is closed. The cap is chambered to receive the upwardlyprojecting flange 10 on the shell 2 surrounding the neck 3 and has acentral recess 11 and a stud 12 depending centrally of the recess.

The inverted cupped latch member 13 is a reciprocating fit within thisrecess, the latch member having a central opening 14 therein to receivethe stud 12. Keeper engaging lugs 15 are struck outwardly from the sidewall 16 of the latch member. Tongue-like springs 17 are struckdownwardly from the top of the latch member.

These spring members are supported by the supporting disk or plate 18which is clamped upon the end of the stud 12 by means of the screw 19, aspring washer 20 being arranged between the head of the screw and thesupporting plate. The supporting plate preferably has anannular-shoulder at 21. The latch member is thus yieldingly supportedand its supporting springs are well protected.

The gasket 5 embraces thelatch member and is retained in assembledrelation thereon by means of the lugs 15; that is, it cannot drop oflfrom the cap.

The stud 12 is non-circular, rectangular in the embodiment illustrated,the opening 14 in the latch member being correspondingly shaped so thatits rotation relative to the cap is prevented.

I have illustrated and described my improvements in a very practicalembodiment as adapted for use on automobile radiators. I have notattempted toillustrate or describe various other modifications oradaptations as it is believed this disclosure will enable those skilledin the art to embody or adapt the same as may be desired;

Having thus described my invention, what claim as new and desire tosecure by Letters Patent, is: v r I 1. In a closure, the combination ofa neck having an inturned flange providing a gasket seat and havingoppositely disposed segmental cammed keepers on the edges thereof, a caphaving'an annular rib-like gasket seat opposed to said gasket seat onsaid neck and provided with an internal recess and a stud disposedcentrally of the recess, an inverted cupped latch member arranged insaid recess and having a central opening to receive said stud and keeperengaging lugs struck outwardly from its side walls, said latch memberalso having a plurality of integral tongue-like spring members struckdownwardly from the top thereof, and a supporting plate mounted on saidstud on said cap in supporting relation to said spring members.

2. In a closure, the combination of a neck provided with keepers, acap-having an internal recess and a stud disposed centrally of therecess, an inverted cupped latch mem- F100 ber arranged in said recessand having a central opening to receive said stud and keeper engaginglugs struck outwardly from its side walls, sa1d latch member also havinga plu- 5 rality of integral tongue-like spring members struck downwardlyfrom the top thereof, and a supporting plate mounted on said stud onsaid cap in supporting relation to said spring members.

In witness whereof I have hereunto set my hand. 4
